Powering Freight’s Destination to Zero

Powering Freight’s Destination to Zero

Last month, Cummins Inc. (NYSE: CMI) and Knoxville Locomotive Works, Inc. (KLW) announced the next step in Tier 4 locomotive repower programs. Building on successful sales of KLW EPA Tier 4 certified and CARB verified locomotives across the U.S., KLW has recently completed the remanufacture of an existing line-haul freight locomotive utilizing the Cummins 4,400 horsepower Tier 4 certified QSK95 engine system. The locomotive also employs a CAF Power & Automation AC traction system along with components from other rail industry suppliers.

Of the KLWX 4400 ACT4 locomotive, KLW Chairman Pete Claussen, said:

“While much of the industry focus has been on developing new technologies to meet 2030 sustainability goals, KLW has developed solutions to help Class 1 operators move closer to their 2030 and 2050 sustainability commitments. The combination of Cummins QSK95 Tier 4 engine and SCR aftertreatment system, along with other components in the locomotive, provide better fuel economy and more reliability over other Tier 4 power packages.”

Regina Barringer, Cummins Global General Manager, Rail and Defense, said:

“We are excited to showcase our clean diesel technology in freight locomotives. Many rail operators have committed to reach net zero emissions and we are confident that the QSK95 will play an important role to helping rail operators improve the emissions for both their current and future line up of locomotives.”

The KLWX 4400 ACT4 locomotive is currently running on Canadian National Railway where it is undergoing reliability growth testing. KLW anticipates commercial availability of the KLWX 4400 ACT4 in the second half of 2023.
